When your oh-my-claudecode setup feels broken or outdated, this diagnostic skill runs seven checks to pinpoint the problem. It compares your installed plugin version against the latest release, hunts for legacy bash hooks that cause duplicate behavior, verifies your CLAUDE.md has the right OMC markers and version tags, confirms Ruby is installed for Ralph workflows, and flags stale cache or curl-installed content that's now redundant. The output tells you exactly what's critical, what's just a warning, and what needs cleanup. It's the first thing to run when OMC stops behaving or after you've upgraded and aren't sure everything migrated cleanly.
